What are TPBS84 Back Turning Inserts used for?
TPBS84 Back Turning Inserts are designed for CNC back-turning and specialized rear-side machining operations where dedicated cutting geometry is required.
What is back turning?
Back turning is a machining operation used to remove material from the rear side or specific recessed areas of a component using a suitable turning tool configuration.
What is the difference between back turning and front turning?
Front turning generally focuses on accessible front or external surfaces, while back turning is designed for machining rear-side, recessed, or otherwise less accessible areas.
Can TPBS84 inserts be used for CNC machining?
Yes. The TPBS84 series is designed for CNC turning applications, with the exact tooling configuration depending on the machine, tool holder, workpiece, and machining conditions.
Can Shenzhen Xinminghui Diamond Tools Co., Ltd. customize carbide inserts?
Yes. Customized insert solutions can be developed according to customer drawings, samples, dimensions, machining materials, and specific tooling requirements.
